Just saw that DriveThruRPG is having a sale encouraging people to buy a new game in the new year, so they’ve cut the price on a number of core books, including the Twentieth Anniversary Edition of Shadowrun 4. They’re dropped the price 3 bucks, making the PDF only $11. You can find full information on the sale and the link for SR4A here. (http://rpg.drivethrustuff.com/rpg_newyear.php?page=2) I’d move quick, because the sale ends on the 17th. Tell your friends–now’s a great time to plunge into the award-winning core rulebook for Shadowrun!
